XIAO RP2350 is a tiny USB-C board based on Raspberry Pi RP2350 MCU

The XIAO RP2350 is an upgrade to Seeed Studio’s XIAO RP2040 board with a more powerful Raspberry Pi RP2350 dual-core Cortex-M33 or dual-core RISC-V microcontroller found in the just-launched Raspberry Pi Pico 2 board. The new Raspberry Pi RP2350 USB-C board has the same form factor but adds eight more GPIOs on the bottom with pads for a total of 19 GPIOs, and we lose two LEDs for serial port connectivity. Most people will still be fine with the XIAO RP2040, but if you need a more powerful microcontroller, extra memory, a few extra GPIOs, and built-in security, then the XIAO RP2350 will be an improvement. XIAO RP2350 specifications: Microcontroller – Raspberry Pi RP2350 MCU CPU – Dual-core Arm Cortex-M33 processor @ 150MHz (Note: again RISC-V is not mentioned at all by Seeed Studio, like for the Cytron MOTION 2350 Pro board) Memory – 520KB internal RAM 8KB OTP Storage […]

Cytron MOTION 2350 Pro – A Raspberry Pi RP2350 board for robotics and motor control

As mentioned in the Raspberry Pi Pico 2 article, third-party RP2350 boards are already available, and one of them is the MOTION 2350 Pro board from Cytron designed for robotics and motor control. The board features a DC motor driver capable of controlling up to 4 brushed DC motors with voltage ratings from 3.6V to 16V. It also features eight 5V servo ports, eight GPIO ports, and three Maker ports for sensor or actuator modules. Each I/O is matched with its own LED which makes the board ideal for the education market and also simplifies debugging. Finally, a USB 1.1 host port is present to connect peripherals such as the RF dongle for a joystick or a keyboard. Cytron MOTION 2350 Pro specifications: Microcontroller – Raspberry Pi RP2350 CPU – Dual-core Arm Cortex-M33 processor @ 150MHz (RISC-V cores are not mentioned, so they are likely not used at all) Memory […]
